Il est trois heures et demie de l'après-midi.

Pronunciation: eel eh twah eur eh duh-mee duh lah-preh-mee-dee

Meaning: It is half past three in the afternoon.

In French, you add "et demie" (and half) for times ending in :30, but only for feminine hours like "trois heures" (3 o'clock); for masculine nouns like "midi" (noon), you would say "midi et demi."
